This bar/lounge is definitely a great alternative to the 2 other bars located on the Casino floor of Luxor.
My cousins and I were just looking for a place to chill/relax and get some drinks. We hadn't seen each other in a while and wanted to catch up. We dropped by Aurora (located near the check in desk) but there wasn't an empty seat or table available. Next we went to Flight, but that bar was packed with people waiting to possibly enter the LAX nightclub.
Thankfully we came across Liquidity in the middle of the casino floor. It wasn't crowded at all, and were able to find a table with lounge chairs instead of just sitting at the bar. The bar is located in the middle and surrounded by sections with lounge chairs/tables/couches that allow Luxor guests some comfort while enjoying their drinks.
I have to admit that although we were in the middle of the casino, it didn't seem as noisy since we were away from the crowds checking in, as well as those waiting to gain access to LAX. It definitely seemed more spacious than Flight but not as roomy as Aurora.
Bottom Line: A welcome and comfortable alternative to the Aurora and Flight bars/lounges.
